»Volatile organic compounds (VOCs) are important indoor air pollutants produced by evaporation at room temperature from paints, wood, fabrics, cleaning agents, air fresheners, cosmetics, furnishings and floor and wall coverings. Indoor VOC levels exceed those outdoors, and are further increased by cigarette smoking and if a garage is attached to a house. Greater use of VOC-containing products has, together with more effective insulation and less external ventilation of modern buildings, contributed to increased VOC exposure. The possible health effects of indoor VOC exposure are a cause for concern, given that people in general, and children in particular, now spend most of their time indoors«
